I think it depends on several things;
 
mostly, how big is the antenna, and is it 'torque neutral'?
 
is the rotor under- or over-rated by the mfg?
 
located on a mountaintop, or up more than 140', or both?
 
whats your budget? (for replacing busted rotators).
 
do you like to climb, or do you hire it out?
 
25 years ago I planned to go no larger than a Tailtwister, with 3 105' towers 
and
3 300 degree sidemounts; longest boom 53'; the rotors were marginal. I never 
lost a rotor.
I NEVER pinned a mast either. tighten the nuts 5 ft pounds short of stripping. 
DID
have slippage on something about twice a year.

Hi All..
  My Yaesu G-1000DXA manual say's to drill thru the mast & put a bolt
thru the rotator & mast to keep it (the mast) from turning in the clamp. I
was told to do a survey here & get everyone's input on doing this as it
might be a bad idea..
                         Thanks for your input!
                            73'..Tom  N3ZC
